DescriptionCVE.org

A improper neutralization of special elements used in an sql command ('sql injection') vulnerability in Fortinet FortiDDoS-F 7.2.1 through 7.2.2 may allow attacker to execute unauthorized code or commands via <insert attack vector here>

AnalysisAI

SQL injection in Fortinet FortiDDoS-F 7.2.1-7.2.2 allows authenticated remote attackers to execute unauthorized code or commands with high impact to confidentiality, integrity, and availability. The vulnerability resides in the web management interface and requires low attack complexity with no user interaction. No public exploit identified at time of analysis, with EPSS data not yet available for this recently disclosed CVE.

Technical ContextAI

FortiDDoS-F is Fortinet's dedicated DDoS mitigation appliance providing inline protection against volumetric and application-layer attacks. This vulnerability affects versions 7.2.1 through 7.2.2 and stems from CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The flaw indicates inadequate input validation or parameterization in SQL query construction within the management interface, allowing malicious SQL syntax injection. The CPE identifier cpe:2.3:a:fortinet:fortiddos-f:*:*:*:*:*:*:*:* confirms this affects the FortiDDoS-F application platform. SQL injection vulnerabilities in network security appliances are particularly critical as these devices typically operate with elevated database privileges and contain sensitive configuration data, attack signatures, and traffic analysis records.

RemediationAI

Organizations should immediately upgrade affected FortiDDoS-F appliances to a patched version as specified in Fortinet's security advisory at https://fortiguard.fortinet.com/psirt/FG-IR-26-119. The advisory reference FG-IR-26-119 indicates Fortinet has acknowledged and addressed this vulnerability through their standard PSIRT process. Until patching is complete, implement compensating controls including restricting management interface access to trusted IP addresses only via firewall rules or access control lists, enforcing strong authentication with multi-factor authentication where possible, monitoring administrative access logs for suspicious SQL syntax patterns in request parameters, and ensuring all administrative accounts follow least-privilege principles. Review and rotate credentials for all administrative accounts as a precautionary measure. Disable remote management access if operationally feasible until patches are applied. Consult the official Fortinet advisory for specific upgrade paths and any additional mitigation guidance for your deployment model.
